HEAT CONTROL FOR OIL BURNERS Filed Sept. 26, 1936 Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE 4 Claims.

My present invention relates to oil burners and more particularly to an attachment for oil burners which increases the heat and directs it over and around the oven compartment of the stove in which the oil burner is used.

Many stoves in which oil burners are used including combination gas and oil ranges fail to produce quick heat in the oven compartment when the oil burner is in operation. This failure is due in some cases because the heat generated from the oil burner has a natural tendency to rise straight up from the oil burner and while the top of the stove over the burner can be heated very hot yet little heat is produced in the oven. This condition is particularly noticeable in combination gas and oil ranges in which the passage over the oven has been greatly reduced due to the space occupied by the gas burners.

While I have shown my invention in the form of an attachment to be used with a standard oil burner it is to be understood that I may combine my improvement, in certain respects, with certain conventional parts of an oil burner thereby simplifying the construction.

The principal object therefore of my invention is an improved oil burner for kitchen ranges and the like;

Another object is an improved heat control for oil burners which is adapted to increase efficiency of the said oil burner;

Still another object is an improved heat control for oil burners which directs the heat from the burner over the top of the oven of the stove in which the oil burner is located;

And still another object is an improved heat control for oil burners and the like which is capable of directing the heat over the oven or up under the covers of the range at the will of the operator, and

Other objects and novel features comprising the construction and operation of my invention will be apparent as the description of the same progresses.

In the drawing illustrating the preferred embodiment of my invention,

Fig. 1 shows a broken outline of a conventional gas and oil range, a conventional oil burner being shown in solid lines, to which my invention has been attached;

Fig. 2 is an enlarged plan view of my new attachment with its cover in place;

Fig. 3 is a bottom plan view of the attachment with the cover removed, and

Fig. 4 is a cross-section taken on the line 4-4 of Fig. 2.

Referring more in detail to the drawing, ID

indicates a conventional oil burner unit mounted in the usual manner in a combination gas and oil range II the burner being provided with the conventional perforated sleeve I2 which is cylindrical in shape.

My improved attachment is composed of three major parts and is adapted to attach to the sleeve I2 of the burner.

At I3 I have shown a secondary sleeve which comprises a sheet metal member, the side adjacent the oven being open and the ends I 4 extending beyond the center of the sleeve I2 in the direction of the oven side of the burner.

Some oil burners are provided with sleeves similar to sleeve I2 but varying in heighth also some burners vary in heighth so that the top of the sleeve I2 may be lower or higher with respect to the top of the oven. This is important with my device if the best results are to be obtained. I have found by actual experiment that my heat deflecting top member I5 should be positioned approximately one inch higher than the front edge I6 of the stove oven II. Having the above various sittings of oil burners in mind I have devised a means of overcoming these variations by providing a sleeve I3 with a series of offset lugs I8 which are struck out from the sleeve I3 and which are adapted to engage over one side of the top of the burner sleeve I2, the lugs being on the inside and the sleeve I3 being on the outside. I may provide several sets of these lugs, the drawing showing two sets, which is optional. In assembling my attachment, it is first determined where the proper heighth should be and then cutting off any surplus material and lugs below the lugs to be used. In this manner one design of the sleeve I3 is made to fit any heighth desired.

To the top of the sleeve I3 I attach a top member I5, previously referred to. This top member comprises a flat top having a downwardly extending flange III the inside face of which is.

designed to snugly receive the top edge of the sleeve I3. It will also be noted that the flange I9 is eliminated on theside adjacent the oven. Pins which are either cast on the top I5 or inserted otherwise are provided to engage on the inner side of the sleeve I3 and act to bind the sleeve I3 against the inner surface of the flange I9 when in place. In the central part of the top I5 I have provided an opening 2| within which is fitted a cover 22.

When the cover 22 is removed the heat from the burner rises against the top of the stove or the bottom of the stove covers. While this use of the apparatus operates in the same manner as in an oil burner without my attachment, with my attachment the heat is more effective on the top of the stove because the sleeve I3 and the flat top of the member I5 around the opening 2i concentrate the heat under the stove top and prevents such heat from being wasted around the front side of the stove below the top. This is one of the principal effects of my invention but when it is desired to bake in the oven II, the cover 22 is placed in the opening 2I and the heat is then prevented from rising directly to the top of the stove and is directed over the top of the oven and into the draft passages indicated by the arrows, the natural chimney draft carrying the heat around the oven.

Under ordinary conditions, without my attachment, the heat from the oil burner has a tendency to rise to the top of the stove in the compartment indicated at 23 and becomes trapped there instead of flowing freely over the oven. This is very noticeable in combination gas and oil range construction in modern stoves in which the gas plates are below the stove top over the portion occupied by the oil burner.

In the top surface of the top member I5 I have also located slots 24 in the front edge of the opening 2| so that the oil burner may be lighted without removing the member I5 with the conventional torch usually provided for the purpose.

It should also be noted that while I deflect and direct the heat over the oven when the cover 22 is in place, at the same time, the radiated heat from the cover 22 and top member I5 is considerable and a hot stove top is always present when the oil burner is in operation.

I also wish to point out the fact that I may build an oil burner incorporating my device therein and in such construction the sleeves I2 and I3 would be one piece preferably but having the same general shape and contour as in the present showing. In either case it should be understood that the sleeve portion I3 is preferably not perforated as in the case of the sleeve I 2.

In actual practice, the direction of the flame from under the top member I5 is so effective that the visible flame from the burner II] can be seen Well over the center of the topof the oven I! in much the'same manner as in a coal range in which wood is being used with a good draft.

While I have described my invention some what in detail yet it is to be understood that I may vary the shape and design of my apparatus within wide latitude within the spirit of the invention.

Having thus described my invention what I claim as new is:

1. A heat control for oil burners and the like comprising in combination, a sleeve partially surrounding the outer sleeve of a conventional oil burner, a plurality of lugs located on the lower sides of said sleeve being adapted to engage over the upper edge of an oil burner sleeve, a top heat deflector member engaged over the said first sleeve, means for attaching said top to said first sleeve, an opening located in the central portion of said top member, a cover adapted to fit in said opening, torch lighter slots located in the top member and communicating with said opening, said slots extending beyond the outer periphery of said cover.

2. A heat control attachment for oil burners and the like comprising in combination, a sleeve partially surrounding the outer sleeve of a conventional oil burner adjacent its top end, a flanged top fitted over said first sleeve and having an opening in its central portion, a cover adapted to engage in said opening.

3. A heat control and director comprising an oil burner sleeve open on one side adjacent the top, a top plate located on said sleeve and having an extended deflector edge projecting out over the open portion of said sleeve, a removable cover in combination with said top member adapted to direct the flame of said oil burner out under said projecting edge of said topmember.

4. A heat director for oil burners comprising, an outer sleeve, a top cover member engaged on the upper edge of said sleeve and being further provided with an outwardly extended top portion, the said sleeve being further provided with a cut-away opening directly below the said extended top portion.
